We specialize in DPF cleaning, and diagnosing. We clean (Diesel Particulate Filters, and Catalysts on ALL diesel engines, from Heavy trucks, tractors, generators and even your front end loader for the farm. We wanted a solution for when people have problems with low fuel mileage, low power and overall a poor running vehicle. When replacing a DPF or Catalyst it can be very costly, this way we can clean it to new spec without having to pay thousands for a new one. If we can't clean it, we don't charge.
